The Deepdene is a 104.52 carat yellow diamond widely considered to be the largest irradiated diamond in the world.

The Deepdene gets its name from the Pennsylvania estate of Mrs. Bok, wife of Cary W. Bok, both the diamond’s original owners. At the time, the Deepdene weighed slightly more at 104.88 carat and was mounted in a diamond clip.

Harry Winston bought the diamond from the Boks in 1954 and it eventually found its way to a London firm in 1960 and later to a German owner.
